“…Recent reports of composites with inorganic and organic additives in conjugated and insulating polymer matrices are covered, as well as the techniques needed to fully characterize their TE properties. [7] Methods for addressing these issues can be found elsewhere. Under most conditions, s, a, and k are interdependent, with increased s giving decreased a and increased k. [4] Thus, optimization of one factor can have a detrimental effect on another.…”

This review covers recently reported polymer composites that show a thermoelectric (TE) effect and thus have potential application as thermoelectric generators and Peltier coolers. The growing need for CO2-minimizing energy sources and thermal management systems makes the development of new TE materials a key challenge for researchers across many fields, particularly in light of the scarcity or toxicity of traditional inorganic TE materials based on Te and Pb. Recent reports of composites with inorganic and organic additives in conjugated and insulating polymer matrices are covered, as well as the techniques needed to fully characterize their TE properties.

“…The advantages of WHR include a decrease in the consumption costs, equipment sizes, pollution, and auxiliary energy consumption. Though a lot of WHR systems are available, the thermoelectric generator (TEG) is a green energy source and a promising energy harvesting device, which is widely used in automotive, military, and battery charging applications.…”

Summary This research work presents a thermoelectric energy harvesting system comprises of a double input DC‐DC converter with maximum power point tracking (MPPT) technique under varying temperature conditions (VTCs). The converter has two inputs with N stages of diode‐capacitor to boost the output voltage. It has the advantages of higher voltage gain and flexibility of power‐sharing by both the independent sources. The perturb and observe (P&O)‐based MPPT algorithm is an efficient and simple method to track the maximum power. However, the power‐current (P‐I) characteristics of the thermoelectric modules exhibit multiple peaks at VTCs; it fails to identify the global peak point (GPP) and gets track the local peak point. To overcome the drawback of the P&O technique, a particle swarm optimization (PSO)‐based MPPT technique is implemented to track the GPP. A comparison is performed between the P&O and PSO technique in terms of MPPT tracking efficiency and oscillation around the maximum power point. From the acquired results of simulation and experiment, it is recommended that the PSO‐based MPPT technique has furnished better overall performance.

“…The thermoelectric conversion efficiency can be improved by increasing ZT and/or the difference between T h and T c . TEGs have been demonstrated on vehicles using commercially available bulk thermoelectric materials [5][6][7][8]. However, automotive TEGs have not become an economically viable technology due to low conversion efficiency and lack of inexpensive and reliable thermoelectric modules (TEMs) that can withstand thousands of high-temperature (>600°C) thermal cycles.…”

a b s t r a c tAutomotive fuel efficiency can be increased by thermoelectric power generation using exhaust waste heat. A high-temperature thermoelectric generator (TEG) that converts engine exhaust waste heat into electricity is simulated based on a light-duty passenger vehicle with a 4-cylinder gasoline engine. Strategies to optimize TEG configuration and heat exchanger design for maximum fuel efficiency improvement are provided. Through comparison of stainless steel and silicon carbide heat exchangers, it is found that both the optimal TEG design and the maximum fuel efficiency increase are highly dependent on the thermal conductivity of the heat exchanger material. Significantly higher fuel efficiency increase can be obtained using silicon carbide heat exchangers at taller fins and a longer TEG along the exhaust flow direction when compared to stainless steel heat exchangers. Accounting for major parasitic losses, a maximum fuel efficiency increase of 2.5% is achievable using newly developed nanostructured bulk half-Heusler thermoelectric modules.
